问题：
I don't understand how looping over a dictionary or set in python is done by 'arbitrary' order.我不明白循环字典或在 python 中设置是如何按“任意”顺序完成的。
I mean, it's a programming language so everything in the language must be 100% determined, correct?我的意思是，它是一种编程语言，所以语言中的所有内容都必须 100% 确定，对吗？ Python must have some kind of algorithm that decides which part of the dictionary or set is chosen, 1st, second and so on. Python 必须有某种算法来决定选择字典或集合的哪一部分，第一、第二等等。
What am I missing?我错过了什么？
